BOTTLE OR JAR CLOSURE.

Specification o f Letters Patent.

Patented May 5, 1908.

Application filed March 11, 1907. Serial No. 361,798. I

ive closure, which can be readily applied and detached, can be used over and over again,

and when in place, constitutes a complete and effective closure and seal that is not liable to become accident-ally loosened or detached.

The preferred embodiment of the invention is shown in the accompanying drawings, wherein:

Figure 1 is a side elevation of the upper portion of a jar, showing the improved closure in position thereon. Fig. .2 is a vertical sectional view therethrough but showing the closure locked. Fig. 3 is a detail sectional view, but showing the closure unfastened or in a position to be removed. from the jar. Fig. 4 is a side elevation of the closure member. Fig. 5 is a bottom lan view of the structure. Fig. 6 is a simi ar view with the closure member, shown in section, and in locked position.

Similar reference numerals designate cordrawings.

The jar or bottle, designated by the reference numeral 7, maybe of any suitable structure, and the neck 8 thereof is provided with an outstanding annular rib 9, the lower shoulder 10, formed thereby, being preferably inclined.

T he improved closure consists of a closure member 11 that is in the form of a cap having a top wall 12 and a depending annular flange 13 that surrounds the neck of the bottle, and extends below the rib 9 thereof. This flange is provided with sets of spaced transverse slits 14 defining between them a plurality of spring jaws 15 that have-inset transversely disposed ribs 16 preferably formed by stamping the material of the jaws inn'ardfv, as shown in Figs; .2 and 4. A slot 17 is formed in the flange at one side of each cork or other suitable material. structure, as long as the ribs 20 of the clampjaw, and is disposed longitudinally of said flange, the said slots beingabove the ribs 16. A clamping member is employed that is in the form of a ring 18 rotatably mounted on the flange 13 of the closure member and having an enlar ed upper portion '19 that is preferably roug ene The ring extends over the jaws, as will be evident by reference to Fig. 1, and it is provided with inset actuatin rlbs 20 that are arranged to seat themse yes in theslots 17, or'to engage the outer portions of the jaws 15 accordin ly as the ring is rotated. The closure mem er or cap preferably carries within it a suitable packmg cushion 21 that comprises a disk of In this ing member are located inthe slots 17 the jaws will be alined with the remainder of the flange 13, and the device can be slipped freely'upon or removed from the neck of a bottle, jar, or other suitable container.

When in place thereon, however, if; the ring is rotated so that the ribs 20 ass'over the jaws 15, said jaws will be force inwardly by said ribs, and the retaining ribs 16 of the jaws will engage the inclined shoulder 10 of the annular rib 9 of the neck. Conse uently, the closure member will be secure y fastened upon the bottle neck, and the ribs 16 riding against the inclined shoulder 10, will draw the closure. downwardly so that the upper edge of the neck ofthe bottle will be forced into snug engagement with the packing cushion 21, and an effective seal WflltllllS be produced To removethe closure, it is only necessary torotate the ring in an op osite.

direction until the ribs 20 are returne into their'respective slots '17, whereupon the jaws will 'swingoutwardly, and the device can be detached. It will thus be evident that a simple closure is produced which will. effectively seal the mouth of a jar'or bottle, and

which can be removed and replaced without i 2. A closure of thecharacter described,

comprisin a closure member having a depen 1ngange provided with spaced slits and a longitudinal slot at one side of and in communication with one of the slits, said slits defining a yielding jaw between them and a clamping ring rotatably mountedon the flangerand having an inset rib that is movable between posltiens in; the slot and against the jaw;

3. A closure of comprising a closure member having a depending flange, including ring engagmg j and having slots between sald jaws,- a continuous ring completely covering and rotatable upon the flange, saidnring having inset ribs movable between positionsin the slots and a ainst the jaws.

4. g losure of the character described, comprising a closure member having spaced jaws, said jaws being provided with inwardly stamped r1bs at their lower ends, and a clamping ring rotatably surrounding the jaws and the character described,.

having inwardly stamped ribs that operate between positions in the spaces between the jaws andagainst the outer sides of said jaws.

5-. A closure vof the character described, comprising a closure member that'consists of a cap havln a depending flan c, said flange being slitte neck engaging aws, sai disposed at one side of the jaws, and a clamp to define a dplura ity of spring cap havingslots ing ring rotatably mounted on the flange and 7 having inset cam elements normally located the jaws to urge the sameinwardly.

6 A closure of the character described, comprising a closure member that consists of a cap having a dependin flange, said flange being transversely slitte to roduce a pluin the slots of the flange and movable against rality of jaws, and said jaws aving ribs on their inner sides, the flange furthermore being provided with slots disposed at one side of the jaws, a'packing cushion located inside the cap, and a ring rotatably mounted on the flange and having inset cam ribs normally located in the slots of the flangeand movable against the outer sides of the jawsto force the sameinwardly.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses. I I cARL JOHA-N LUNDQUIST, Witnesses:
